Movie black technology

The fuel element is actually a nuclear fuel after processing, and the appearance looks like a piece of block shape, which is similar to that of the electronic battery commonly used in front of the watch, but it is necessary to enlarge some.

"The expected indicator is the same as before?" Chen Shen determined.

On the other side, turn it to the corresponding page number, "According to the current calculation, the ceramic nuclear fuel generated after the new method is handled can achieve the ideal protection rate."

The so-called ceramic nuclear fuel is a nuclear fuel used in the form of a difficult melting compound, with the current universal level, after this treatment ensures 98% of the radioactive fission substances, only neutron and gamma rays with strong penetration capacity Radiate.

However, the system technology is different.

Zenglean has a number from the document. "According to expectations, the new ceramic nuclear fuel should ensure that 99.8% of the radioactive fissile substances are not essential, and we have to put nuclear fuel into the alloy matrix, which can give ceramic high melting points and The irradiation stability is characterized by better strength, plasticity and thermal conductivity, etc., further increasing safety. "

"This is even if the fuel element cladding cracks, the outer layer of metal substrate can also reduce the leakage of fission products."

Things related to the core, the first thing to consider is security, and the microconuclear reactor is even more.

The special treatment outside the nuclear fuel is the first line of defense, and the second line of defense is the alloy matrix outside the ceramic, except for the two defense lines, there are other defense lines.

It can be said that the weight of the nuclear reactor 16 tons of weight is used to prevent leakage.

Chen nodded, "Then, the fuel component is produced, and the design of other programs must also be seized, and we are only nine months."

"There is no problem with the supply of 239?"

Qilong, responsible for the production process, active opening: "We have been applying for the application, it is estimated that these days can be available."

"That is."

Nuclear fuels used above Tibetan antelopes are not the most familiar uranium 235, but is 239.

This is also a kind of nuclear fuel.

To say that 239 has to talk about uranium such elements, uranium elements have uranium 235 and uranium 238.

However, there is only a fission reaction between uranium 235 and 238 to occur, and uranium 238 can only be considered a nuclear waste, and in nature, the reserves of uranium 235 are approximately 0.7% compared with uranium 238, and the number is extremely rare.

Since the number of uranium 235 is rare, then relatively, the most in the uranium ore in nature is uranium 238.

The plumbin 239 can be obtained by bombarding uranium 238 with a fast neutron, because uranium 238 will absorb fast neutrons with a certain proportion, thereby turning into a plutonium 239, which is equivalent to a waste of waste, and the uranium 238 suddenly The waste is turned into a nuclear fuel available.

The fast neutron is the free neutron generated in the nuclear fission reaction. It is popular to build a reactor with a small amount of uranium 235 or 239, and then put a circle of uranium 238 outside the nuclear fuel, you can wait for the mushroom to grow, After a period of time, open the planting box, it will find that the uranium 238 inside has grown into a plutonium 239.

And the number of generated plutonium 239 is much more than the nuclear fuel used by the reactor, this is still a stable and unrecognized sale ...

This can be easier to extract uranium 235 from uranium ore with thousands of centrifuges. It is a few kilograms or more kilograms of death, no matter whether it is used as a mushroom bomb or a nuclear power plant. Not enough.

And so that the centrifuge for use is less, it is naturally used in the electricity, and it is also more environmentally friendly, and the earth mother has exposed a gratifying smile.

Therefore, many of the first mushroom bosses that want to quickly enter the mushroom planting club, the first mushroom bomb that is manufactured by the country to get rich in the early days.

The current typical is a neighbor next to the day, and before the early fat mushroom bomb, it is a bomb.

The nuclear reactor of Tibetan antelope is also designed based on this principle of this uranium. It should be called [fast neutron proliferative nuclear reactor].

This reactor is not the first creation of the system, and some people have thought of it in the last century.

Moreover, there is no more innovation in the structure, compared to the general nuclear reactor, composed of nuclear fuel, reducer, control rod, coolant, reaction layer, and the system's nuclear reactor is only less than one reduction.

Because the effect of the reduction agent is used to slow the neutron velocity generated in the slow fake reaction, so that they become slow neutron from fast neutron, so that the uranium 235 produces a fission reaction. The "heavy water" that the public often hears is one of the reduction replacement. It can reduce the speed of the fast neutron from 14,000 kilometers per second to a few kilometers per second.

The reactor with a fuel is not required to use a reductionler because only fast neutrons can make the plutonium have a fissure reaction.

In addition to the reducer, the design ideas of other parts are not large, the only difference is the advancement of materials and processes.

The biggest breakthrough is that the system breaks through the method of reacting plumanism in the reactor.

In general, the 239 generated in the fast neutron proliferation pile is not directly used, and it is necessary to take out the secondary treatment, and the can be used again as a fuel.

According to the system's technique, it is possible to perform special treatment as the uranium 238 of the proliferative layer, and the uranium 238 after the process is converted into a plutonium 239, and the secondary removal process is not required, and can be sent to the reactor by the mechanical device. Be used as a nuclear fuel.

This is advantageous for reducing the body type of the reactor.

Because at present, the critical quality of spherical plutonium produces fission in the case of neutron reflective materials, that is to say that only ten kilograms can cause fission to generate a chain reaction when it is required to make a spherical shape.

This critical quality is half a hundred kilograms of uranium 235.

In addition, the neutron reflective layer of the Tibetan antelope is a special, efficiency is higher than the current high, and more fast neutrons can be reflected, making nuclear fuels more likely to fissure.

So even if the fuel is not made into spheres, the critical quality can also be reduced to ten kilograms, so that the upper uranium 238 is replaced in the periphery, and the maximum energy can be released with the lightest fuel weight.

After using this technology, add the progress on the material, the core part of the nuclear reactor is designed to be a cylinder, only 85 cm high, and only three meters in diameter, it can be perfectly placed in the top of Tibetan antelope.

"How is the design of the current control stick?"

The problem of nuclear fuel part is solved, and Chen will turn to other parts.

Zenglean quickly turned the information on the screen to another side, "Now the design of the rod has completed the initial plan."
